Kicking up the coffee grinding

Kicked up my coffee bean grinding yet another notch with my drill press.

You can probably see where this is going.

Takes about 40 seconds to grind the entire hopper full of beans.  Tried to get some video, but for some reason my phone only recorded the audio.

Quite effective. The metal spindle and ceramic grinder parts gets pretty hot after grinding though and takes a few minutes to cool down enough to handle.
